Abstract: The Ecuadorian Sierra region is characterized as a relatively high degree of water scarcity, which results in prominent conflict between demand and supply, as well as threat of severe drought. However, this region is a key agricultural development zone with great demand of irrigation expansion. By analyzing the current status of irrigation in the Ecuadorian Sierra region and considering the requirements of water and soil resources along with food security, this paper put forward the overall layout of irrigation development of the Sierra region. Through a series of water storage, water diversion, water lifting and water diversion project and the construction of embankments, sump, combined with water-saving alteration and construction measures, the annual irrigation water supply capacity would be expanded by 1.23 billion m3 in this region, making the effective irrigation area increased from 348 000 hm2 to 507 000 hm2 in 2035.
